CAS:Atorvastatin is a potent inhibitor of the enzyme HMG-CoA reductase, which is responsible for the conversion of HMG-CoA to mevalonate. This inhibition reduces the production of cholesterol and other lipids in the liver. Metabolism studies have shown that atorvastatin undergoes extensive presystemic metabolism by cytochrome P450 enzymes, primarily CYP3A4 and CYP2C9. The drug is converted to inactive metabolites that are eliminated primarily through renal excretion. Atorvastatin has not been found to inhibit any of the following: cytochrome P450 1A1/2, 2C8/9, 2D6, 2E1, 3A4/5 or glucuronidases.Fórmula:C33H33FN2O4Pureza:Min. 95%Cor e Forma:PowderPeso molecular:540.62 g/molDesoximetasone impurity A
CAS:Produto ControladoDesoximetasone impurity A is an impurity found in the drug product Desoximetasone, which is a corticosteroid. It has been identified as an impurity in the drug product and there are no known uses of Desoximetasone impurity A. This impurity was determined to be natural based on its molecular weight, infrared spectrum, melting point, and elemental analysis. The molecular weight for Desoximetasone impurity A is 687.2 g/mol with a melting point at 89°C and an elemental analysis of Carbon: 29%, Hydrogen: 3%, Nitrogen: 16%, Oxygen: 32%.Fórmula:C21H25FO4Pureza:Min. 95%Peso molecular:360.42 g/mol
